misc: Add Lattice ECP3 FPGA configuration via SPI
This patch adds support for bitstream configuration (programming / loading) of the Lattice ECP3 FPGA's via the SPI bus. Here an example on my custom MPC5200 based board: $ echo 1 > /sys/class/firmware/spi0.0/loading $ cat fpga_a4m2k.bit > /sys/class/firmware/spi0.0/data $ echo 0 > /sys/class/firmware/spi0.0/loading leads to these messages: lattice-ecp3 spi0.0: FPGA Lattice ECP3-35 detected lattice-ecp3 spi0.0: Configuring the FPGA... lattice-ecp3 spi0.0: FPGA succesfully configured!
